Hello guys , have got an 820-01987 that does not power from the charger, but works fine on battery. I only get 5V, and PPBUS is 12.3 with charger connected. I have compared diode mode on the LDO of the CD3217 and all seems good , all basic rails for the CD3217 are present: there’s no corrosion anywhere. I couldn’t find a short either: board is spotless. Please help . Thank you
